NAME¶

Class::MakeMethods::Template::Inheritable - Overridable data

SYNOPSIS¶

  package MyClass;
  use Class::MakeMethods( 'Template::Inheritable:scalar' => 'foo' );
  # We now have an accessor method for an "inheritable" scalar value
  
  MyClass->foo( 'Foozle' );   # Set a class-wide value
  print MyClass->foo();       # Retrieve class-wide value
  
  my $obj = MyClass->new(...);
  print $obj->foo();          # All instances "inherit" that value...
  
  $obj->foo( 'Foible' );      # until you set a value for an instance.
  print $obj->foo();          # This now finds object-specific value.
  ...
  
  package MySubClass;
  @ISA = 'MyClass';
  
  print MySubClass->foo();    # Intially same as superclass,
  MySubClass->foo('Foobar');  # but overridable per subclass,
  print $subclass_obj->foo(); # and shared by its instances
  $subclass_obj->foo('Fosil');# until you override them... 
  ...

DESCRIPTION¶

The MakeMethods subclass provides accessor methods that search an inheritance tree to find a value. This allows you to set a shared or default value for a given class, and optionally override it in a subclass.

  bits (?)
  array (?)
  hash (?)

If you just need scalar accessors, see Class::Data::Inheritable for a very elegant and efficient implementation.
